Research output: Contribution to journalArticlepeer-review


Based on the Lyapunov stability theorem, the solution of the Riccati equation, and the convex combination property, we propose some conditions under which the poles of the closed-loop system with real parameter uncertainties can be assigned in the specified region by using linear state feedback. Two types of the specified regions are considered: (i) the region to the left of the Re(s) = - σ and (ii) the disk D (α, γ) with the center (α, 0) and the radius γ. The main feature of this paper is that all the inequalities in the theorems do not contain any uncertain parameters.
